5. Title, number of pages and language(s) of the notified document:  DUS 2 269:2022, 
Composites made from cellulose -based materials and thermoplastics (usually called 
wood -polymer composites (WPC) or natural fibre composites (NFC)) 
  Specifications for 
decking profiles and tiles, First edition; (42 page(s), in English)  
6. Descri ption of content:  This Draft Standard specifies the characteristics of decking 
profiles and tiles made from cellulose -based materials and thermoplastics, usually called 
wood -polymer composites (WPC) or natural fibre composites (NFC), for external use.  
This standard is applicable to extruded profiles but also to tiles manufactured by other 
plastics processing techniques, e.g. injection moulding.  
It is not applicable to kits (i.e. support rail profiles, cover strip profiles and hardware) 
which are out of the scope of this standard.  
NOTE: For editorial reasons, the abbreviation "WPC" is used for "composites made from 
cellulose -based materials and thermoplastics".
